The EZ Twist™ Nose Cap attachment makes accessory changes up to five times faster than using the standard wrench. The EZ495 features an integrated wrench that allows the nose cap to be used as a wrench to tighten or loosen the collet nut when changing Dremel accessories. Because the EZ Twist™ Nose Cap becomes part of your Dremel rotary tool, you’ll always have your wrench at hand and will save time from ever having to look for a lost wrench. Can be used on all Dremel rotary tools with a threaded nose-piece.
